Vermont Gage 111101200 Class Zz Plus Plug Gage 0.012 in

Product Description

The VERMONT GAGE 111101200 is a Class ZZ Plus plug gage machined from tool steel and used to verify bore and hole dimensions with high precision. It has a nominal diameter of 0.012 inches and holds a tolerance of 0.0002 inches, making it suitable for close-tolerance inspection work. The gage has a 10 microfinish surface on the gaging member, which reduces wear and maintains dimensional accuracy over repeated use. Overall length is 2.0 inches. Each unit ships with a Certificate of Accuracy that carries NIST traceability, meeting documentation requirements for ISO and AS9100 quality systems. Machinists, quality technicians, and metrology professionals use this gage for go-type inspection of small-diameter features.

This plug gage is used in manufacturing and machine shop environments to confirm that drilled, reamed, or broached holes meet minimum size requirements. It is also suited for setting and verifying micrometers, verniers, and other precision measuring devices. At 0.012 inches diameter, it falls within the small-wire range, making it appropriate for inspection of fine holes in watch components, fuel injector bodies, medical devices, carburetor jets, and similar precision-machined parts. Fabricated to ASME B89.1 standards, it is a recognized tool in any formal inspection or calibration workflow.

Installation Notes

Plug gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Store in the protective case or sleeve when not in use to protect the gaging surface from contact damage. Before use, verify the gage is at thermal equilibrium with the workpiece, as temperature variation will affect dimensional readings. Calibration and re-certification should be performed at intervals consistent with your quality management plan and applicable standards.
